Letters Patent No.196,07 7, dated October 26, 1869.

IMPROVEMENT IN COMBINED SAW-SET, CDAMP,`AND VISE.

'lhe Schedule referred to in these Letters Patent and making part of the same.

1To all whom this may concern:

Be it known that I, B. BLAcKs'roNn, of Warren, in the county of J o Daviess, and State of Illinois, have invented a new and improved Saw-Set, Clamp, and Vise; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the `art to make and use the same, reference being had to the accompanying drawings, and letters marked thereon, in which- Figure 1 is a perspective representation of my improved tool.

Figure 2, an elevation of one of the jaws, showing the set, and the means for adj nsting it.

Figure 3, a transverse section of that part of the device indicated by the line w, iig. l.

Figure 4, a perspective representation of the sawset, removed from the jaw of the vise.

The present invention relates to an improved tool, which can 'be conveniently usedas a sawolamp, sawset, and vise; and

Its nature consists in the novel manner inwhich the set is constructed, held in place, and adjusted in the jaw of the vise, in combination with other parts of the device, as the whole is hereinafter fully de-` scribed.

A A represent stationary standards, which terminate, at their upper ends, in a jaw, J, and have projecting lugs 'l cast solid to them, for the convenience of fastening the tool to a bench,ror other suitable place, in the usual manner.

Curved standards B B are pivoted to the standards A A at G O, and their upper ends terminate in a jaw, K, similarly constructed to the jaw J.

These jaws are operated by a lever, F, and screw D, the latter passing through a cross-piece, G, cast solidto Athe standards B B, and through a cross-piece, H, cast solid tothe standards A A.

A nut, E, countersunk into said cross-piece H, is prevented from being turned around, when the screw D is drawing the jaws of the vise together.

Each of the jaws J K is provided with an auxil- 'lary jaw, as shown at M L', which have projecting lugs L at their end, to receive the screws b, with which the auxiliary jaws are held to the jaws L M.

The inner face of the jaw L is so recessed out as to receive a set, l? R, Whose ends bear against the shoulders formed by means of extending the lugs L through to the inner face of the jaws, as shown at V V, fig. 2. n This' set is provided with a series of projections, c cc, 85o., which, when the jaws of the vise are shut Together, bend over everyalternate tooth, or, in other set as to give the saw-teeth, shown at d, a greater or.

less auglea wedge-shaped gauge, N, is placed between it-and the auxiliary jaw L', and it is so arranged that when the set-screws O O, with which it isf-astened to the jawL, are turned to draw the gauge upward, the lower edge of said gauge will be moved toward the jaw M, and consequently give the saw-teeth a greater set.

The .operation is very simple, requiring only that the saw-teeth he placed on the iiange R, and the jaws closed, by means of lever F.

When the device is used as a saw-clamp or vise, the set P It can be removed.

Having thus fully described my invention,

What I claim, and desire to secure by LettersPatfent, is y Ihe combination of the set It P, provided with projections c c c, dto., with the wedge-shaped gauge N, jaws J K and L M, and standards A B, as and for the purpose set forth.

B. BLACKSTONE.
